To all whom it may concern.

Be it known that I, EDWARD F. KUNATH, a citizen of'the United States, residing in Jersey City, in the county of Hudson and State cation.

This invention relates to means for adjusting, guiding, and feeding the paper around the cylindrical platens of type-writing machines; particularly those\ of the frontstrike variety, and is of advantage where it is desired to insert a sheet or s eets backwardly from the front of the platen, especially if one or more sheets are already in the machine. I I

It is often desired to insert a sheet at the front of the platen as, for instance, where there is to be written only one line or letter, and that at the bottom edge of the sheet, or where sheets have been bound together and it is desired to add some writing upon one of the sheets, or where it is desired to remove a bill and replace it with a fresh bill-head while a carbon-sheet and a long record-sheet remain in the machine, as in condensed billing or where it is desired to insert a narrow sheet and make a carbon record thereof upon a much wider sheet. These obj edts may be acomplished by making provision for inserting the sheet backwardly, and to this end I have altered the usual deflector-plate, which curves around beneath the platen andcontacts therewith, so that it is separated from i the platen, and when the usual pressurerollers are released a passage is left beneath the platen for the ready insertion of the lead- 'ing edge of a backwardly-inserted sheet from the front of the platen backto the papershelf. I have also made provision for holiding carbon and record sheets stationary,

- against the rear side of the platen duringathei insertion of a fresh sheet or bill-head. i The present improvements relate more particularly, however, to means for facilitating the introduction of the sheet. between the platen and'the curved deflectorrplate at the front edge of the latter and-to means for holding the carbon and record sheets stationaryagainst therear side ofthe platen in such a' manner as to leave a free passage for the backwardly-inserted-sheet up along the papershelf, so that, if desired, sai'd sheet may be pushed back far enough toper nit writing near its top edge.

To facilitate the introduction of asheet at the front of the platen, I provide a plate extending along the platen and sloping upwardly and forwardly therefrom and serving to guide the leading edge of the sheet dowri be.- tween the platen and the deflector-plate,which curves therebeneath. Sa id sloping plate is provided with graduations,which appear upon its upper surface, so that it serves the fuznc- .tion of the usual front scale, its edgewhere it leading edge of"the 'backwardly inserted sheet may slide freely back and up along the paper-shelf as far as may be des red. When a sheet is inserted from the back, it ispassed between said grippers and the platen, and

means are provided for throwing the grippers back away from the platen whennot in use and also for adjusting them along the platen independently of one another.

In the accompanying drawings, Figure 1 is a sectional front elevation of the carriage and part of the framework of an Underwood front-strike writingemachine provided with my present improvements, Fig. 2 is a plan illustrating the relation of my novel front scale 'to the platen. Fig; 3 is a rear elevation of one-half of the front scale on of one of the pairs of scales which'arepivoted'to a bracket secured to the framework of the 'machine and do not travel with the carriage. Fig. 4 is an end elevation of one 'ofthe scales, showing its relation to the platen. Fig. 5 is a se'ctional end elevation of the platen and earfront edge to ifacilitateithe'" intro ria e, showing the platen in its lower or norma case-shift position and the rear grippers thrown away'frorn the platen, the pressurerolls beneath the platen being also in normal position, so that the parts are in position to write 11 on single sheets inserted at the back' of the p aten in the usual manner. Fig. 6 is a plan illustrating paper-shelf, grippers, and appurtenances. Fig. 7 is a view similar to Fig. 5, but showing the platen shifted up to upper-case position to facilitate the introduction of a sheet at the front of the platen;

the pressure-rolls beneath the platen being released 'or thrown down to permit the sheet to be pushed back beneath the platen and the grippers being shown thrown against: the platen to hold stationary any pa er that may be already in. the machine and a so toafiord a pae up alongfthe papen-sheh for the backwardly-nioving' sheet.

The'nsual vertically sh'ftable' cylindrical platen 1'- is journaled by its'axl 2in= ends '3 4 4:,sai ends being inclines forward of the laten frarne, mounted upon a carriage join'edby a plate 5; Whichy and downwardly and .forms' a pa er shelf in-reariof "the'plat'en.

These 'pressuraro is 'are releasable y means of.adepressiblekey12, usuall =pivoted 'uponthe right-hand end-4 of the'p atenframe andeonnectedby a'link 13 to -crank 14' upon release-shaft "15, the latter usually havingfiats or recesses "16', normally occupied yby' arrns' 17,; which rojectfrom ressurearms -18,'that-norrnal 'y bear upon t e shafts oraxles of the rolls. "When the key 12 is (16? I pressed,' the-shaft'-15 is rocked, causing the arms 17 tovibrate, so that the rolls fall away from the platen, as "at Fig. 7. When the rolls are thrown off, a sheet may-be inserted 'backwardly at the front 'ofthe platen and pushed back as far as-de'sired.

To facilitate the introduction'of a" sheet at thefront of the platen, I pivot upon'brackets 20 a pair of'plates 21, one at each side ofthe rinting-point, (indicated at 22 suitable ribon-vibrating devices being rovided at 23 between said plates, as We] as the usual type-guide 24. Each plate is provided with. a spring 25, which presses it toward the and-forwardly frornthe platen, aszati 26.

The bot om of in.

platen, @{id at its upper edge is bent upwardly sloping portion 26- ooh-l eiaeat;

tacts with or lies close to the platen along a ing line upon the platen, so as to facilitate ad ustment of the paper after insertion, the two sloping plates 26 being in line with each length (taken together) approximating the that the leading edge of a sheet of any suitable width may be readily introduced as seen at 27, Fig. 7, between theplaten and the sloping plates'26, the latter guiding the edge of the sheet so that it passes readily down between the platen and the deflectorfi. It will be understood from a comparison of Figs. 5

the lplaten but when the latter is shifted up sertion oft e=paper. I

Upon the top surface of plate 26-gradua- -'tions '28 may be provided at letter-space intervals,- so-that=said plate may serve as a scale, these graduations being easily seen by 'the operator, owing to the forw 11rd slope of the scale. At -their'inner ends the plates2l,

- pivots'up in-front of the platen, are provided with fenders '29 to insure'thatthe plates shall always ride over the usual paper-guidthe platen and are adjustable therealong, and at the outer ends of plates 21 fenders 31 may beprovided for the same purpcse, the endsof' the scales'or seale-sectionsbeingalso bent to form fenders 32.

eiaeaa thereof. Normally the grippers are thrown back out of use, as at Fig. 5, and the paper is inserted forwardly between the grippers and 'the platen, and when the grippers are thrown against the pa er on theplaten, as at Fig. 7, .apassage A is eft for the insertion of a sheet llong" record-sheet, there may be inserted into the machine in the usual way the record- 'sheet, the carbon-sheet, and the bill-head,

the parts being in the positions seen at Fig. 5.

- After Writing the bill it is drawn out, the release-key 12 being usually slightly depressed in order to facilitate the withdrawal of the bill. Then the finger-piece 41 is pushed back,

thereby swinging the fingers forwardly to fas- - I between the platen :and

. and being so mounted that a lease-key 12 'may improvements may be 'gripthe paper against the platenthat is,

the carbon-sheet and the record-sheet. Then fa fresh bill may be inserted backwardly, as indicated by the arrows at Fig. 7, the releasekey 12 being-first pressed all the way-down and the laten-frame being also elevated by the usua means. The paper thus inserted is ad usted approximately tothe required position. If desired, it may be inserted at the rear of the'machine and thrust forwardly.

The release-key 12 is then restored to its normal position, bringing -the pressure-rolls 8 9 again into operation. Then the platenframe may be dropped to normal position. If upon examination the freshly-inserted I sheet is found not to be in the proper position,

the key 12 may be again depressed to cast off the rolls and the paper nicely adjusted by means of the scale 26. Thereupon the rebe lifted and the writing proceed.

I My improvements will also be found of advantage in manipulating sheets in other ways and for other purposes. i

Variations may be resorted to within the scope of the invention, urigid-portions of the ed without others. Having thus described my invention, I claim- I 1.
